Fertility and aging: do reproductive-aged Canadian women know what they need to know?
Fertility and aging: do reproductive-aged Canadian women know what they need to know?
Karla L Bretherick et al.; 2010
Objective
Female fertility declines with age; however, women are increasingly delaying childbearing until later in their reproductive years. One of the factors that may contribute to this trend is a general lack of knowledge about the decline in fertility with age.
Result(s)
Although most women were aware that fertility declines with age, they significantly overestimated the chance of pregnancy at all ages and were not conscious of the steep rate of fertility decline. [!!!] Surprisingly, women overestimated the chance of pregnancy loss at all ages, but did not generally identify a woman's age as the strongest risk factor for miscarriage.
Conclusion(s)
Education regarding the rate at which reproductive capacity declines with age is necessary to avoid unintended childlessness among female academics and professionals.
[A very important question: No they don't! ... and nobody cares.]

"London is arguably the first great western capital city to pass this landmark..."
"A couple of weeks ago it was announced that London no longer contained a
majority from the UK’s main ethnic group, known in the demographers’ jargon as
the “White British”.
London is arguably the first great western capital city
to pass this landmark, though that depends on where you draw the boundaries
around Washington and on excluding Brussels as a special case because it is an
“embassy capital”."
...
"[The] studied indifference of London’s political and media elite appears to be in
sharp contrast to the feelings of many of the white British people who live in
less salubrious parts of the city. For it is important to understand that the
proportion of white British Londoners fell so dramatically – from 60 per cent in
2001 to 44.9 per cent in 2011 – not only because of high levels of immigration
but also thanks to a mass exodus of white Britons."
...
"The "studied indifference of London's political and media elite" shouldn't
surprise anyone, since this is what they wanted all along, but without drawing
anyone's attention to it. So they're not going to draw anyone's attention to it
now."
